'PETER GREGERSEN, OF WAUZEKA, WISCONSIN, ASSIGNOR TO HIMSELF AND PHILLIPMILLER, OF SAME PLACE.

IMPROVEMENT IN FEATHERING PADDLE-WHEELS.

Specification forming part of Letters Patent No. 169.690, dated November9, 1875 application filed September 17, 1875.

State of Wisconsin, have invented anew and Improved Feather-in gPaddle-VVheel, of which thefollowing is a specification:

The invention will tirst be described in eonnection with drawing,andthen pointed out in the claims.

Figure 1 is a side elevation of my improved paddle-wheel. Fig. 2 is afront elevation. Fig. 3 is an elevation of one ofthe paddles. Fig. 4 isa top view. Fig. 5 is a side elevation of one of the arms. Fig. 6 is alongitudinal section of the arms. Fig. 7 is a side eleva-tion ot the camfor working the stops. Fig. 8 is a side elevation ot' a eontrivance forholding the cam and allowing it to shift for working the stops whicheverway the wheel turns. Fig. 9 is an adjusting contrivance for varying thecam to cause it to work the stops earlier or later. Fig. l0 is a sideelevation of contrivance for working the regulator; and Fig. l1 is anelevation of a portion ofthe hub of the paddle-Wheel, showing theconstruction.

Similar letters of reference indicate corresponding parts.

A represents the p'addles, which arehnng by pivots B above the center tothe armsO, so that they can hang vertically edgewise while the wheelrevolves, and so enter and leave the water vertically. D represents thestops to hold the paddles to the water during the time they are to dothe work, and for releasing them as soon as the work is done, to allowthem to rise vertically out otl the water, and enter vertically again.Said stops are fixed in the slots E of the wheel-arms, so that thecorners F of the paddles bear against them untilithey are to be letfree, when the stops are pushed out by the cam Gr beyond the outer edgesof the paddles. said stops being attached to sliding rods H. The rodsare immediately pulled back again by springs I, to be ready for catchingthe paddles again when they enter the water. These rods are guided atthe outer end by the stop, and at the hub of the wheel by thefriction-rollers J, fixed between the ring Kand one ot' the parts L ot'the hub. The cam is xed loosely on the shaft ofthe Wheel, with a stud,M, projecting through the curved slot N of a stationary disk, N, whichallows the cam to shift rightor left as the wheel turns forward orbackward, and holds it in position for working the stops alike, whetherthe wheel turns one way or the other. O is an adjusting-slide, to workup and down over the ends ot' the slot by a screw, P, to limit the rangeof the ca-m in shifting from side to side. The paddles are armed at eachend with a casting, Q, having the pivot B attached in a socket, andfastened by a key, R; also having a slot for a stop, D, and also havingconnections for the tension-braces S. The arms also have a casting, Y,for holding the paddle-pivots and the sliding stops. The hubs ot' thewheel are composed ot' two parts, L, each having notches T, and flangesU and V, for the arms C, which are secured by clamping` them between thetwo parts, and bolting the whole together through the holes W. The armsare also bolted, near the outer end, to the rings X, making a verystrong and substantial construction.

Having thus described my invention, I claim as new and desire to secureby Letters Patentl. The combination ot' paddles A, pivoted above thecenter, the rods having stops D, the cam G, and the springs I, allarranged substantially as and for the purpose specified.

2. The cam Gand slotted disk N', combined with the paddle-wheel and thestop-rods, in the manner described, 1 for changingI as the wheel turnsforward or backward.

3. The combination of adj ustin g-slide O with the shifting-cam and diskN', substantially as specified.

4:. The metal heads Q, having pivot B and tension-rod connections, incombination with a paddle, substantially as specified.
